the sig is nice for the most part imo, but your lighting is the only thing that really stands out (its on the rong side ) the clipping masks look pretty nice on the tag, and the smudging is nice too. an extra suggestion (just for the sake of trying it) would be to apply the image and sharpen it once (not sharpen more, it'd be too much imo, just normal sharpen) and that may brind some facial features out a bit more, erase anythign u dont like and if its too much lower the opacity, but its up to you if you like it or not, i think you're fine leaving it as it is now ^_^ (other than the light )
I agree with Daecu. The only other thing I'd change would be the size of your text for your name, I'd just make it a little bit smaller, but thats just me. Good sig with good potential.
Okay i will change the render to the right place for a light source, but how can i fix it without losing my effects on the render?
the white thing is way to strong nd looks well messed up.Just sort it out a lil use like a soft white brush of 65px and put it on softlight.The text on the right is messed up, there no need to have it on the side.
